Benga coal mine

The Benga coal mine in Mozambique is a metallurgical coal mine being developed by the Australian coal company, Riversdale Mining (65%) with Tata Steel as a 35% joint venture partner. The mine received government approval in January 2010.

The mine is located just to the east of the Revubue River and Zambezi River junction. According to the company, as of January 2011, the project includes 502 million tonnes of coal reserves with the first phase of the mine aimed at annual production of 5 million tonnes (run of mine). The first phase of the mine is scheduled to be commissioned by the end of 2011. The company has stated that full production for the mine could be 20 million tonnes per annum with hard coking coal production of 6 million tonnes and export thermal coal of 4 million tonnes.

Associated with the project, Riversdale have proposed the construction of the Benga Power Plant, a 2000 megawatt coal-fired power station. (The company have proposed that stage one of the project would be 500MW with a later expansion contingent on the upgrading of the transmission line).

Background
In its 2006 annual report the company stated that in July 2006 it had purchased four separate tenements in the Lower Zambezi Coal Basin of Mozambique. "The tenements cover an area of approximately 203,000 hectares and represent a significant strategic holding in the Moatize Coal Province. This province is considered to be one of the largest known undeveloped coking and thermal coal regions in the world. Riversdale anticipates completing acquisition of the licences in Mozambique during September 2006. Riversdale will undertake an intensive exploration program on targeted tenements in Mozambique with a view to fast-tracking development of sustainable long-term mining operations, with an initial focus on metallurgical coal resources," the company reported.

The company's primary focus was on the Benga licence area in the Moatize area which was adjoined by licences held by the Brazilian company, Companhia Vale do Rio Doce (CVRD). Riversdale reported that "a major feasibility study is being undertaken by CVRD to establish a major coal mine with associated rail and port facilities on its concessions containing 2.4 billion tonnes of coking and steaming coal. Based on geological evidence, the coal bearing series being mined at a nearby coal mine and intersected by CVRD on their licences extends across the Benga Licence. Coal outcrops on the Benga Licences, and data from drilling on each side of the Benga Licence, creates a strong likelihood of hard coking coal resources across these licences." The company stated that its initial intention was to develop plans for a 2 million tonne per annum export project. It also stated that "it is envisaged that further exploration will help identify thermal coal resources with a view to establishing the viability of local power stations."

The U.S. Geological Survey reported in its 2007 survey of the Mozambique mining industry that "in December 2007, Riversdale Mining Ltd. of Australia announced the signing of a joint-venture agreement with Tata Steel Ltd. of India to develop a mine in the Moatize coalfield. Tata purchased a 35% share in the Benga and the Tete licenses that were held by Riverside. Resources at Benga were estimated to be about 1.23 billion metric tons."

The Australian commodities forecasting agency, ABARE noted in March 2010 that "Riversdale is planning to develop the Benga project (3.3 million tonnes). However, because of the extent of development required (mining and infrastructure), export capacity is not assumed to be completely utilised" by 2015.

In a December 2008 presentation to investors, Riversdale Mining outlined the licence area of the Benga coal project. (A larger more detailed version of the map can be accessed ).

Markets
As part of the joint venture agreement, Tata Steel has committed to take 40% of the coking coal from the mine. A further 10% of the mine's output has been tentatively committed to Wuhan Iron and Steel Corporation (WISCO).

Relocation of residents
As part of the mine development plan, Riversdale plan to relocate 500 families to a new village 50 kilometres from the mine site. In its 2010 annual report the company stated that as part of phase 1 of the mine "approximately 59 households need to be relocated ... Preparations for the relocation of the affected families are progressing well with construction of the host town at Mwaladzi on schedule. This follows official Government approval of the Riversdale Resettlement Action Plan (’RAP’) and the subsequent construction license approval by the Provincial Resettlement Committee. The Mwaladzi village will eventually accommodate in excess of 500 families relocated from the Benga concession area."

Infrastructure
In March 2011, Australia's Riversdale Mining said it will invest $46 million in locomotives to carry coal from its Benga coal mine in Mozambique to Beira port. Riversdale will buy 11 locomotives and 200 railcars for the rail line. According to Bloomberg, the locomotives and railcars will probably be delivered in April 2011 before the mines starts exporting coal in September 2011. The Benga mine is expected to produce 5.3 million metric tons (mt) of metallurgic coal a year by the second half of 2011, some of it for the proposed Benga Power Plant. Output may rise to 20 million mt of met coal a year by 2013, of which 10 million mt will be exported. The project, jointly owned by Tata Power's Tata Steel, has an estimated coal reserve of 502 million mt.
